What are fan guns?

Fan guns are propeller-driven machines, sometimes referred to colloquially as snow cannons. For many years, only mobile fan guns were used. As snow making technology developed, stationary installations were implemented to avoid set-up times. Fan guns are characterized by a long projection, high snow output, low wind sensitivity and flexible use. Therefore they are mainly used on wide slopes, in areas with a high demand for snow, steep terrain or open areas exposed to wind.
